Patent number: 7263804Abstract: A vehicle door, wherein a drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires are laid are provided at upper and lower sides of a base panel. The glass plate is moved up and down by driving the wires, and the glass plate is prevented from moving in a vehicle inward direction when the door is closed. Wire fixing portions are prevented from being damaged by large upward and downward stroke movements of the glass plate Furthermore, the wires are prevented from slackening when the wires are driven and stopped by providing a supporting rod along a path of upward and downward movement of the glass plate, and a contact member which has no contact with the supporting rod. Trumpet-shaped guide portions are provided at hole edges of the wire fixing portions, and the V-shaped circumferential surfaces of a tensioner eliminates slack in the wires.Type: GrantFiled: November 12, 2004Date of Patent: September 4, 2007Assignee: Kabushikikaisha AnseiInventors: Koji Ishii, Shinichi Nishikawa, Takashi Nishio, Yoshihiro Ando

Patent number: 4917489Abstract: A light beam spot size measuring device comprises an optical magnifying system. The magnifying system receives an image of the recording light beam spot formed within an optical recording apparatus, and magnifies it. Then the converter receives the magnified image of the beam spot formed on the pickup surface thereof so as to produce an output signal representing the size of the beam spot. An attenuator device attenuates the intensity of the image of the laser beam spot during magnification. The image of the beam spot therefore can be currently measured on the basis of the output signal even with the high intensity of the recording light beam.Type: GrantFiled: December 2, 1988Date of Patent: April 17, 1990Assignees: Pioneer Electronic Corporation, Pioneer Video CorporationInventors: Takashi Nishio, Tomoyoshi Ikeya, Chiharu Koshio

Patent number: 4627725Abstract: A device for monitoring the amount of deviation of a light beam in an optical system with which the freedom of design of the system is significantly improved. For each position at which the amount of deviation is to be measured, a beam splitter is provided to divide the light beam at that point into a main beam and a sub-beam. The sub-beam is applied to an optical position detector which detects the amount of deviation of the sub-beam from a predetermined position on the detector, that deviation being related to the amount of deviation of the main beam from its designated optical path. The output of the position detector is used to correct the position of the main beam.Type: GrantFiled: April 18, 1984Date of Patent: December 9, 1986Assignee: Pioneer Electronic CorporationInventors: Takashi Nishio, Tomoyoshi Ikeya
